PRINTING-PRESS ATTACI-HWENT.

Specification of Letters Patent;

Patented Jan. 21, 1908.

Application filed May 9. 1907- Serial No. 372.666-

To all whom it may concern:

Be it known that I, ALEXANDER J. Hoop, a citizen of the United States,residing at Muscoda, in the county of Grant and State of Wisconsin, haveinvented certain new and usefullmprovements in Printing-PressAttachments; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to improvements'in attachments for platen printingpresses, and more particularly to one by means of which bronzing,tinting, numbering, and the like, may be done while the printed sheet isupon the platen.

One object of the invention is to provide a simple, inexpensive andeffective attachment of this character, by means of which a rubber stampor form, a numbering machine, a

' bronzing or tinting pad or any similar device may be swung down uponthe printed sheet upon the platen after the usual impression has beenmade upon the sheet, and while the inking rollers are moving down overthe usual type form to re-ink the same.

Another object of the invention is to improve and simplify theconstruction and operation of devices of this character, and therebyrender the same more perfect and efficient.

With the above and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts, hereinafter described and claimed.

In the accompanying drawings,-Figure 1 is a side elevation of a jobprinting press with my improved attachment applied thereto, the partsbeing shown in two positions in full and dotted lines; Fig. 2 is a topplan view of the same; Fig. 3 is a perspective view of thespring-supported arm and its attached parts,

. removed from the press; Fig. 4 is a detail view of the swin ing memberwhich carries the form holder; Fig. 5 is a detail transverse sectionalview through the two adjustable sections of the spring-supported arm;Fig. 6 is a perspective view of the bracket which supports the triproller, the inking roller, and the bronzing or tinting powder; Fig. 7 isa vertical sectional view through the bronzing or tinting box; Fig. 8is-a perspective view of the trip arm which is secured to the throw-offlever of the press; Fig. 9 is a perspective view of the tinting pad;Fig. 10 is a side view of the tinting mechanism, the tinting-box beinshown in section; and Fig. 11 is a sectiona View of the printing pad.

Referring to the drawings by numeral, 1 denotes a job printing press ofthe well known Gordon type, which comprises a stationary frame 2, a bed3 uponwhich the usual form is clamped, a laten' '4, an inking disk orplate 5, and inking rollers 6, which are mounted in the usualoscillating frame 7.

My improved auxiliary printing, tinting or numbering attachmentcomprises a spring .9 of substantially U-form, which has one of its ends10 bent, as at 11, and is clamped to one edge of the swinging rollercarrying frame 7, by twoor more clips 12, or in any other suitablemanner. The other arm 13 of the spring 9 has boltedor otherwise securedupon it, as at 14, an angular arm 15, whichis preferably provided uponits free end with an adjustable extensible member or section 16. Theextensible section 16 of this arm is slidably and adjustably secured tothe section 15.

by'forming in the outer end of the latter a slot 17, which is adapted toreceive an inte gral lug or stud 18 formed upon one face of the section16, which has upon its outer threaded end a washer and a winged clampingnut, by means of which the section 16 may be clam ed against movement.The section 16 is a so provided with a perforated lug or extension 8,through which a shouldered thumb nut 8 projects, and engages with ascrew-threaded lug 19, which is adjustably clamped to the arm 15 by anut 20. The arm 15 is made adjustable to permit the rubber form,numbering machine, tinting pad or similar device, which is mounted uponits free end, as hereinafter explained, to be adjusted so that it willstrike the desired point or place upon the platen or the sheet of paperthereon, and the impress of such form, pad, or similar device, may beregulated by means of a set-screw 21, which is provided in the threadedopening in the lower portion of the arm 15, and has its end impingingagainst the bent portion 11 of the spring 9.

The rubber form', numbering machine, tinting pad or similar device 23,which the attachment is to operate is secured in a suitable holder 24,which is adjustably clamped upon a swinging frame or element 25, mountedupon the outer end of the extensible section 16 of'the arm 15. Thisswinging frame or element 25 is here shown in the form of a castingconsisting of an open body 26 having at one end a cam-shaped trip arm orlever 27, and at its opposite end a slotted arm 28, which is adapted toextend transversely with respect to the printing press. In the bodyportion 26 of the frame or member 25 is a pivot 29, which is mounted ina suitable bearing 30 provided upon the outer end of the extensiblemember 16 of the arm 15. This frame or member 25 is adapted to be heldnormally in engagement with a stop screw 31, provided in a threaded lug32 upon the arm section 16 bymeans of a coil spring 33,

which has one of its ends connected to the frame 25, and its other endto a bracket or extension 34 upon the lower portion of the section 16 ofthe army 15. By adjusting the stop screw 31, the form, machine, pad, orother device 23, may be adjusted so as to strike flat upon the platenwhen the press is in operation; The holder 24, shownin Figs. 1 and 2 ofthe drawings, comprises a body 35 having an overhanging lip 36 at oneend to engage one end of the block or pad of the form 23, which isclamped upon one face of the body 35 by an adjustable plate 37, which issecured by means of a bolt 38, passed through a slot 39 in the end ofthe body 35, and having a winged nut 40 upon its threaded end. The body35 of the holder has projecting from its opposite side a rod or stem 41,which is adjustably connected with the arm'28 by means of a slotted bar41 and two nuts 42 and 42. The rear end of the bar 41 is perforated,through which passes a thumb nut 43, which engages with a lug 43 thatis,

adjustably secured to the arm 28 by a clamping bolt 43.

Instead of employing the holder 24, any suitable clamping device may beused for holding a numbering machine, or when the bronzing or tintingpad 44, shown in Fig. 9 of the drawings is employed, its spring arm 45can be adjustably connected with the arm'28 by means of the bar 41, aswill be readily understood. By mounting the arm 15 in this manner'uponthe swinging roller carrying frame 7 of the press, it will be seen thatas the said frame is oscillated to move the rollers alternately acrossthe usual form upon the bed 3 and the inking disk 5, the device 23 willbe alternately moved into engagement with the platen or the printedsheet thereon,

and under the inking pad or roller 46, which is supported at the rear ofthe press.

The inking device 46, which is in the form of a soft or flexible pad ofabsorbent material, is mounted upon a spring frame 47, whichisadjustably secured by means of a clamping screw 48 in the slotte-douterend ofabracketarm 49, which is adjustably secured upon a bracket frame50, bolted or otherwise attached to the stationary portion 2 of theframe in the rear of the inkingdisk 5. Upon this frame 50 is alsoadjustably mounted, asat 51, an arm 52, which has adjustably mounted inits slotted outer end a trip roller 53,which is disposed in the path ofthe cam-shaped trip arm 27, provided upon the frame 25, so that when thearm 15 is swung rearwardly, said trip arm 27 will pass under the roller53 to cause the frame 25 to be swung upon its pivot 29 to bring the formor device 23 under and into contact with the inking device 46. When thearm 15 is swung forward and the trip arm 27 leaves the roller 53, thespring 33 will return the swinging frame 25 to its normal position, inengagement with the stop screw 31.

When it is desired to use the attachment for bronzing or tinting matterthat has been printed upon the paper or sheet upon the platen 4, the pad44 is adjustably secured upon the arm 28 of the frame 25, so that whenthe arm 15 is swung rearwardly, said pad willbe moved into the open endof the box or receptacle 55, which contains the bronzing or tintingpowder. This receptacle, as shown, is supported from the frame 50 and isrectangular in form. Its interior is lined with fur, or other suitablematerial 56, which is adapted to hold in suspension the bronzing ort1nting powder, and at a suitable pointin its upper portion is provideda hopper57,

which has in its bottom adjustable slides 53. The latter have theiropposing edges covered with fur, or other suitable material, so that thepath of a lug or projection 61, formed.

upon one side of the swinging frame 25. This trip arm 60 is here sh ownin the form of a metal rod bent and secured to the lever 59 by a clamp62.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention, as defined by theappended claims.
